Which of the following can lead to traumatic telecanthus?

Traumatic telecanthus refers to an increased distance between the inner canthi of the eyes, often resulting from trauma. This condition commonly occurs due to disruption of the soft tissue or bony structures that support the eyes and the surrounding facial anatomy.

Periorbital lacerations can directly affect the eyelid and the surrounding soft tissues. They can cause damage or disruption to the structures that maintain the position of the eyes and can lead to changes in the alignment of the medial canthus. Such injuries can cause the eyes to be positioned further apart than normal, thereby leading to telecanthus.

In the context of facial fractures, while frontal bone fractures, zygomatic arch fractures, and maxillary fractures can also affect the overall architecture of the midface and eye region, the specific mechanics of telecanthus are most directly associated with soft tissue injuries, such as those caused by periorbital lacerations. Thus, the internal soft tissue changes are pivotal in the development of telecanthus, which is why this option is the most appropriate choice in this context.
